Title: Detector for defects in magnetic medium of large capacity storage system and its detecting method
Inventor: KERII SHII GUROOBAA
IPC: H04L25/06
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To detect the position and seriousness of defects or damage of a magnetic recording medium by detecting transfer signals and calculating in a read operation. SOLUTION: FIR 48 imparts an individual equalized signal to a viterbi detector 54 and a differential circuit 50, while the viterbi detector 54 analyzes this signal to form a digital data output corresponding to the data stored in a disk/ head assembly 12. With a read channel 18 operating at a defect scanning mode, transfer signals 56 supplied by a metric circuit 53 are combined into one signal using a selected circuit 69. Thus, the transfer signals 56 are capable of detecting the position and seriousness of defects or damage of a magnetic recording medium by digitizing either positive transfer or negative transfer.

Abstract: PROBLEM TO BE SOLVED: To quickly obtain pattern division result, in an electron beam wring pattern forming method having a pattern division process for dividing a polygonal figure into a plurality of basic patterns which can be written with an electron beam aligner. SOLUTION: In a pattern classification process 11, an input pattern group is classified in basic patterns and other polygonal patterns. Only the input patterns classified in the polygonal patterns are sent to the next pattern division direction estimation process 12. In the process 12, in order to evade generation of basic patterns having fine widths, it is estimated from configuration information such as edge lengths and vertex positions of the inputted polygonal pattern whether the polygonal pattern may be divided horizontally by division lines in the (x) coordinate axis direction or divided vertically by division lines in the (y) coordinate axis direction. In the next pattern division execution process 13, the polygonal pattern is horizontally or vertically divided into a plurality of basic patterns according to the estimation result.

Title: Preparation of molded synthetic resin article from fluidized polymerizable substance
Inventor: YAMADA TAKAO
IPC: B29C43/00
Filed: 1983-06-10
Abstract: PURPOSE:To make it possible to repeatedly use a gasket and to obtain a molded article faithful to the surface state of a mold, by moving each heat exchanger by transmitting the thickness change based on the volumetric change of cell content to the same through a compression spring. CONSTITUTION:The volume of the content in each cell 6 changes according to the advance of polymerization reaction but pressing force generated by the reduction in the interval of heat exchangers 1 at both ends is transmitted by each compression spring 10 and each heat exchanger 1 small enough in moving resistance is easily moved by the pressing force of the compression spring 10 and intervals between the cells 6 are equally reduced. Because the reduced portion of the interval between the heat exchangers at both ends corresponds only to the sum total of the thickness reduced portion caused by the volumetric reduction of the content in each cell 6, a gap and pressing force are not generated at all between the content and the heat exchange surface 1a in each cell 6. Therefore, a molded article becomes faithful to the surface state of a mold, that is, the heat exchange surface 1a.
